# Freebuff

> Freebuff is the free coding agent: a free CLI coding agent and Freebuff Web, the free way to build full-stack apps. No subscription, no setup, no lock-in. The free alternative to Claude Code, Cursor, Codex, Lovable, Replit, Bolt, Windsurf, and Devin.

Freebuff has two products, both free:

- **Freebuff CLI** — a free AI coding agent for your terminal. Install with `npm install -g freebuff`, then run `freebuff` in any project. It edits code, runs commands, and ships features autonomously. Supported by text ads shown in the CLI; no subscription or credit card required. Works on macOS, Windows, and Linux.
- **Freebuff Web** (https://freebuff.com/web) — a free full-stack web app builder. Describe the app you want and it builds, hosts, and deploys it. The free alternative to Lovable, Bolt.new, Replit Agent, and v0.

Freebuff is built by the Codebuff team (https://codebuff.com) on the same agent framework.

- and more.

After every response, it generates 3 clickable follow-up suggestions so you always know what to do next.
